Log in to our site. From the top of the page click on My Profile. In the "Profile" header line, at the far right, you will see an Edit Profile link. Click on it. From there you can manage all your profile information, including Two Factor Authentication (TFA).
Please note that when you set up TFA you are also automatically creating a set of backup codes. Following the procedure I explained above you can click the pencil icon next to the Backup Codes entry in the TFA section to view and/or regenerate them. Print them out and store them in a safe place. If you lose your phone you can use any of these codes instead of your regular TFA method to log into our site and disable TFA. Backup codes are single use, meaning that after you use one of them it's "burned" and cannot be used again. You get ten of them and you can regenerate them whenever you want so you'll realistically never run out of backup codes.
